Dial-up Connections 7

To create a dynamic dial-up connection between two NetBlazers you need

to configure the same things at both ends of the connection. If a dial-up

connection named for your NetBlazer is not set up on the NetBlazer at the

opposite end of the connection, your dial-up connection will fail.

Figure 7-1. A Dial-up LAN-to-LAN Connection

Dial-up interfaces are used for both inbound and outbound connections.

For outbound connections, when your NetBlazer receives a packet with an

address that is on a remote network, your NetBlazer checks for an existing

connection with that remote site. If a connection does not currently exist,

your NetBlazer selects a modem, ISDN line, or Frame Relay connection and

calls the remote NetBlazer.

When a connection is established, the answering NetBlazer tries to authen-

ticate the connection. In order to be authenticated, the calling NetBlazer’s

name and password have to be in the answering NetBlazer’s dial-up config-

uration files. Once the connection is validated, the two NetBlazers can send

packets to each other through the dial-up connection.
